What is the place value and face value of a digit?
Q: What is the place value and face value of a digit? A: Place value is the value of a digit based on its position in a number (e.g., in 352, 5 has place value 50). Face value is the actual value of the digit (5 remains 5).
How do you find the LCM and HCF of two numbers?
Q: How do you find the LCM and HCF of two numbers? A: LCM (Least Common Multiple) is the smallest number divisible by both numbers. HCF (Highest Common Factor) is the largest number that divides both numbers exactly. Methods: prime factorisation or division method.
What is the difference between factors and multiples?
What is the difference between factors and multiples? A: Factors are numbers that divide another number exactly. Multiples are numbers you get by multiplying a number by an integer. Example: Factors of 12 are 1, 2, 3, 4, 6, 12; multiples of 3 are 3, 6, 9, 12, etc
What are prime numbers, and how do you identify them?
Q: What are prime numbers, and how do you identify them? A: Prime numbers are natural numbers greater than 1 that have only two factors — 1 and the number itself. Examples: 2, 3, 5, 7, 11. To identify them, check if they are divisible only by 1 and themselves.
